Abstract

The utility model relates to an electromagnet for hoisting a large-scale round billet, and is characterized in that the electromagnet comprises a U-shaped iron core (1); the U-shaped iron core (1) has a downward opening; coils (2) are winded on two vertical sections of the U-shaped iron core (1); a housing (3) is disposed outside the coils (2); the housing (3) is made of a manganese steel magnetism isolating plate; oversize magnetic plates (4) are disposed at both end parts of the U-shaped iron core (1); the lower surfaces of the oversize magnetic plates (4) are arc concave surfaces. According to the utility model, two coils are disposed on the U-shaped iron core, which increase the magnetic force; the attracted weight is great, and the energy consumption is less; the oversize magnetic plates at the end parts of the U-shaped iron core are provided with arc concave surfaces, which can form surface contact with a round billet well, and has good stability.

Description

The large-scale round steel billet of handling is used electromagnet

Technical field

The utility model relates to a kind of electromagnet, relates in particular to the large-scale round steel billet of a kind of handling and uses electromagnet, belongs to the lifting electromagnet field.

Background technology

Along with the development of China's continuous casting technology, generally adopt the continuous casting round steel billet to produce the wind power generation main shaft, but the handling work efficiency of continuous casting round steel billet is very low always; Many enterprises still adopt the steel rope pocket to hang the primitive method of handling; Also have enterprise to adopt lifting electromagnet to come the handling round steel billet, production efficiency improves, yet contacting of round steel billet and magnetic pole is generally line and contacts during the lifting of this type lifting electromagnet; Be difficult to the large-scale round steel billet of normal lifting; Also be prone to the phenomenon that steel billet falls,, have only by increasing a.t. and satisfy the handling requirement owing to fail to solve the little problem of contact surface all the time; Make that the volume and weight of electromagnet is very big, the big anharmonic ratio of still inhaling of power consumption is very little.And general electromagnet has only a coil, and suction is difficult to reach certain requirement, needs a plurality of electromagnet to work simultaneously like this, and use cost is high, and production efficiency is low.

Summary of the invention

The purpose of the utility model is to overcome above-mentioned deficiency, provide a kind of inhale great, the power consumption less, stability the high large-scale round steel billet of handling use electromagnet.

The purpose of the utility model is achieved in that the large-scale round steel billet of a kind of handling uses electromagnet; Comprise the U-iron core, the opening of said U-iron core all is wound with coil on the two vertical sections of said U-iron core down; The outside of said coil is provided with shell; Said shell is made by the manganese steel magnetic isolation plate, and the both ends of said U-iron core are equipped with and add large magnetic plate, and the said lower surface that adds large magnetic plate is an arc-shaped concave.

Compared with prior art, the beneficial effect of the utility model is:

The utility model U-iron core is provided with two coils and has strengthened magnetic force, inhales greatly, and power consumption is few; The large magnetic plate that adds of the end of U-iron core is provided with arc-shaped concave, can well contact with round steel billet formation face, has stability preferably.
